BEST AVAYLABLE COPY lUNITED"S'TMI-1S 1 A i SEMEON SKERPAN, OF DETRQI'l, 'MICHIQANLH fri Application led August 7, 1924. 'Serial No. y730,661;` ""'H This 'invention relates to new and useful improvements in envelopes.

' The primary object of this invention is to provide an envelope with an improved form of closing or sealing means.

A further object of the invention is to provide-a novel body ,portion of an envelope and improved means for connecting the parts to form the same. v Other objects and advantages of the 1nv-.lvention will be apparent during the course of the following description.

vInv-tbe accompanying drawings forming a part. of this specification and in which -like numerals are employed to designate :like parts throughoutthe same,

Figure-1 illustrates in plan view the blank Vemployed for forming -the envelope before the edges of the same have been gummed,

Figurei2lillustrates a plan of the envelope after the edges have been gummed and two flaps employed for forming the body portion of the envelope properly connected,

Figure 3 illustrates a plan view of the envelope after all of the flaps employed for forming the body portion of the envelope have been connected and sealed together,

Figure 4 illustrates a longitudinal sectional view of the envelope showing the closure flap with its sealing tongue folded down in engagement with the body portlon of the envelope and further illustrates said sealing tongue prior to the sealing of the same to the said body portion,

Figure 5 illustrates a similar view to Fig. 4 with the sealing tongue carried by the closure flap sealed to the body portion of the envelope,

Figure 6 illustrates a transverse sectional view taken upon lines VI--VI of Fig. 3,

Figure 7 illustrates a transverse sectional view taken upon line VII-VII of Flg. 8, and

Figure 8 illustrates a plan view of the envelope after it has been sealed closed.

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of this invention, in Fig. 1, the numeral 5 illustrates .the front wall of the body portion of the envelope, to one longitudinal edge of which isv integrally formed the bottom flap 6 having the outwardly converging edges 7 which terminate in the blunt point 8. Formed transversely of the bottom flap T in proximity to the blunt end are the spaced slits 9 which extend in parallelism to each otherQ'f'The. bottom ,i flap. 6; is further provided 'with a.,longitudinally extending slot l0 which has a length substantially equal to the distance betweenv the parallel slits 9 and has its ends terminating in close prox-imity'to the inner ends of said slits 9.

This bottom flap v6 is intended to be folded l l uponthe front wall 5 of the body portion of theenvelope on the dotted line- -a-. Formed integrally with the end edges of Ythis front wall5 are the end fiaps 11 and 12 which are of substantially.' triangular formation and have thepbifurcated tongues 13 and 14 formed at the 'outer ends thereof. The Vfurcations lgand 16 of these bifurcated tongues .13 andf 1,4 are 4of unequal size, the furcations.4 T15. vbeing smaller than' the furcations 1 6 and intended to be folded upon the lines TU-,the furcationsl, beingintended tofbe unfolded respect to theend flaps 11 and 12. These end flaps are intended to be folded upon the dotted lines -c-. The remaining edge of the front Wall 5 of the body portion of the envelope has formed integrally therewith the closure flap 17 which is provided with the integrally formed sealing tongue 18 at its outer edge. It is intended that the edges 11 and 12 of the end fla s 11 and 12 and the furcations l5 of these aps be gummed, as illustrated in .',onnection with the end flap 11 in Fig. 2. The outer edges of the closure flap 17 are intended to be gummed as illustrated in Fig. 2 and the sealing tongue 18 is also intended to be gummed.

In forming the body portion of the envelope, the bottom flap 6 is first folded upon the line -afor causing it to overlap the front wall 5. Either end Hap 11 or 12 may then be folded upon the line -c for causing its gummed edge to be lmoved into engagenient with the outer face of the bottom flap 6 to which it is sealed. The furcation- 15 is intended to be inserted through the adjacent slit 9 for the purpose of permitting its gummed surface to be sealed to the inner face of the bottom flap 6. The remaining furcation 16 of this end flap is illustrated as overlying the portion of the vbottom flap positioned between the parallel slits 9. The remaining end flap should then be folded upon its dotted 1in e -cand connected to the bottom flap in the same manner as described in connection with the first end flap. The body portion of the envelope is now ready for receiving a letter or the like.

To .-seah theenyelqpe, :the v.closure fizvlp'l? is to lili, foleik-.ulotnhe liodjl'piton-'ff the envelope, at the line -dand the sealing tongue 18 should thenbe `inserted 4into t11e, envelope through theslo'lO. 'The `gun`ineo portion of this sealing tongue should; v.1 e`r 1 be forced against the inner surface of the portion of the bot-tomaeflap,.positionedbe# tween the parallel slits 9 und sealed thereto, ns best illustrated .inFigs.'5 en d 7; The 4en- :rs-'clope-isnov ina proper condition to Abe 'mailed=.?fff A v i 5P; will :readily be seen i that the' bodypor- -tion :of'tlxe-rlenvelope `has- 'its 'endflaps not is toghe ltalengasn preferredvegznnpleof the sinne, :indi-that Vil-rions-oliinges'v inthe shape, size, und arrangement of parts may be rcsorteglto vwitlunit(:lelgzu'ting from the spirit z'of "the"itentiorwche scope of the subjoined claim.
